IUCN status: Vulnerable
EPBC Predator Threat Rating: Not assessed
IUCN claim: “Eastern Barred Bandicoots probably disappeared from the mainland due to introduced predators and habitat destruction from introduced herbivores.”
Cats hunt locally-born bandicoots (Lenghaus et al. 1990; Dufty 1994; Schwarz 1995; Woolley et al. 2019) and reintroduced bandicoots (Lenghaus et al. 1990; Winnard & Coulson 2008; Groenewegen et al. 2017).
Bandicoots have co-occurred with cats on Tasmania since 1820 and on the mainland for 167 years (Current submission).
There are no studies linking cats with eastern barred bandicoot
population trends. In contradiction with the claim, the two species
continue to co-occur in Tasmania after over two centuries and they
co-occurred on the mainland for over a century-and-a-half.
Evidence linking Perameles gunnii to cats. A. Systematic review of evidence for an association between Perameles gunnii and cats. Positive studies are in support of the hypothesis that cats contribute to the decline of Perameles gunnii, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance. B. Last records of extirpated populations relative to earliest local records of cats. Error bars show record uncertainty range. Predator arrival records were digitized from Abbott 2008. See methods section in [current submission] for details on evidence categories.
